[0109] Below, refer to Figure 7 , Figure 8 A hinge device according to a second embodiment of the present invention will be described. Figure 7 is an exploded perspective view of a schematic configuration of a hinge device according to a second embodiment of the present invention, Figure 8 It is a figure which shows the arrangement|positioning of the stopper on the bracket plate used for the hinge apparatus of the 2nd Embodiment of this invention.

[0110] The difference between the hinge device of the second embodiment and the hinge device of the first embodiment is that a stopper 11 is provided on the first rotation center shaft 10 , and a stopper 11 is provided on the bracket plate 20 to abut against the stopper 11 . The block 33. The rest of the structure is basically the same as that of the hinge device of the first embodiment, and the same members are assigned the same symbols and detailed description thereof will be omitted.

Abstract

The invention provides a hinge device and a portable terminal, wherein the hinge device is capable of opening and closing 360 degrees stably and smoothly. The hinge device comprises a first rotating central shaft and a second rotating central shaft, support plates, cams, cam engaging parts, press force applying devices, stopping parts and stopping blocks. The first rotating central shaft and the second rotating central shaft are supported by shafts in a mutually parallel manner, the first rotating central shaft and the second rotating central shaft are arranged on the support plates and are enabled to rotate optionally, the cams and the cam engaging parts are arranged on the first rotating central shaft and are applied with force by the press force applying devices, the stopping parts are arranged on and rotate with the second rotating central shaft integrally, and the stopping blocks are arranged on assigned positions of the support plates and correspond to the stopping parts of the second rotating central shaft. The stopping parts of the second rotating central shaft are enabled to abut against the stopping blocks to limit the rotating angle of the second rotating central shaft. When the hinge device is in action, the second rotating central shaft stops rotating if the stopping parts of the second rotating central shaft abut against the stopping blocks, and the first rotating central shaft responds to further-applied acting force to start rotating.

Description

technical field [0001] The present invention relates to a hinge device for a portable terminal such as a notebook computer in which two housings are expandably and closedly connected in a layout, and a portable terminal having the hinge device. Background technique [0002] At present, in portable terminals such as notebook computers, so-called clamshell hinge devices that can be folded and opened and closed are often used, that is, a cover portion having a display portion and a main body portion having a key operation portion are connected in a foldable manner. [0003] As such a clamshell hinge device used in a portable terminal, various structures have been proposed in recent years. Patent Document 1 proposes a biaxial hinge structure in which a linking belt such as a rope is connected to one hinge body, and after connecting the two shafts, it is connected to the other hinge body so that the biaxial hinge rotates in the opposite direction. linked in a way. However, the ...
